LaMachine is a unified software distribution for Natural Language Processing. We integrate numerous open-source NLP tools, programming libraries, web-services, and web-applications in a single Virtual Research Environment that can be installed on a wide variety of machines.
The software included in LaMachine tends to be highly specialised and generally depends on a lot of other interdependent software. Installing all this software can be a daunting task, compiling it from scratch even more so. LaMachine attempts to make this process easier by offering pre-built recipes for a wide variety of systems, whether it is on your home computer or whether you are setting up a dedicated production environment, LaMachine will safe you a lot of work.
We address various audiences; the bulk of the software is geared towards data scientists who are not afraid of the command line and some programming. We give you the instruments and it is up to you to yield them. However, we also attempt to accommodate researchers that require more high-level interfaces by incorporating webservices and websites that expose some of the functionality to a larger audience.
A) Guided installation with custom build option (recommended)
To build your own LaMachine instance, in any of the possible flavours, or to download a pre-built image, open a terminal on your Linux, BSD or MacOS system and run the following command:
bash <(curl -s https://raw.githubusercontent.com/proycon/LaMachine/master/bootstrap.sh)
This will prompt you for some questions on how you would like your LaMachine installation and allows you to include precisely the software you want or need and ensures that all is up to date. A screenshot is shown at the end of this subsection.
Are you on Windows 10 or 2016? Then you need to run this command in a Linux subsystem; to do this you must first install the Linux Subsystem with a distribution of your choice (we recommend Ubuntu) from the Microsoft Store. Follow the instructions here. Are you on an older Windows or you are on Windows and want a VM and not a custom build? Then this won't work you have will to use a pre-built Virtual Machine as explained in installation path C.
Building LaMachine can take quite some time, depending also on your computer's resources, internet connection, and the amount of software you selected to install. Half an hour to an hour is a normal build time. The bootstrap script alternatively also offers the option to download pre-built images (installation path B & C).
B) Pre-built container image for Docker
We regularly build a basic LaMachine image an publish it to Docker Hub. The above installation path A also offers access to this, but you may opt to do it directly:
To download and use it, run:
docker pull proycon/lamachine docker run -p 8080:80 -h latest -t -i proycon/lamachine
This requires you to already have Docker installed and running on your system.
The pre-built image contains the stable version with only a basic set of common software rather than the full set, run
inside the container to select extra software to install. Alternatively, other specialised LaMachine builds may be available
on Docker Hub.
If you want another release, specify its tag explicitly:
docker pull proycon/lamachine:develop docker run -p 8080:80 -h develop -t -i proycon/lamachine:develop
C) Pre-built Virtual Machine image for Vagrant (recommended for Windows users)
We regularly build a basic LaMachine image and publish it to the Vagrant Cloud. The above installation path A also offers access to this (except on Windows), but you may opt to do it directly.
To download and use it:
- Ensure you have Vagrant and VirtualBox installed on your system. Windows users also have to make sure that Hyper-V is disabled in Control Panel → Programs → Turn Windows features on or off → Hyper-V
- Open a terminal or command prompt
- Navigate to a folder of your choice (this will be the base folder, files inside will be shared with the VM)
vagrant init proycon/lamachinefrom the terminal, this creates a file named
Vagrantfilein a text editor and change the memory and CPU options to suit your system (the more resources the better!).
- If you are on Windows and don't have a decent text editor, just use wordpad (not Notepad nor MS Word!)
vagrant upfrom the terminal to boot your VM
vagrant sshfrom the terminal to connect to the VM
The pre-built image contains only a basic set of common software rather than the full set, run
inside the virtual machine to select extra software to install.
To stop the VM when you're done, run:
vagrant halt. Next time, navigate to the same base folder and run
vagrant up and
vagrant ssh again.
LaMachine includes a wide variety of open-source NLP software. You can select which software you want to include during the installation procedure (or any subsequent update).

For a verbose list of installed software and its metadata, run
lamachine-list once you are inside your LaMachine
installation. For more information regarding software metadata, check the corresponding section in the the contributor
If you enabled and started the webserver in LaMachine, then you have access to a rich portal page giving an overview of all installed software and providing access to any software with a web-based interface. This portal is powered by Labirinto.
LaMachine is open for contributions by other software projects, please read the contributor documentation.
LaMachine can be installed in multiple flavours:
- Local installation - Installs LaMachine locally in a user environment on a Linux/BSD or macOS machine (multiple per machine possible)
- Global installation - Installs LaMachine globally on a Linux/BSD machine. (only one per machine)
- Docker container - Installs LaMachine in a docker container
- Virtual Machine - Installs LaMachine in a Virtual Machine
- Remote installation - Installs LaMachine globally on another Linux/BSD machine. (only one per machine)
In all cases, the installation is mediated through Ansible, providing a level of abstraction over whatever underlying technology is employed. Containerisation uses Docker. Virtualisation is made possible through Vagrant and VirtualBox. The local installation variant uses virtualenv with some custom extensions.
Initially, the user executes a
bootstrap.sh script that acts as a single point of entry for all flavours. It will
automatically download LaMachine and create the necessary configuration files for your LaMachine build, guiding you
through all the options. It will eventually invoke a so-called ansible playbook that executes installation steps for all
of the individual software projects included in LaMachine, depending on your distribution and flavour.
LaMachine uses Debian as primary Linux distribution (for virtualisation and containerisation), we generally support the following platforms (but certain participating software may not support all!):
- Debian 9 (stretch) - This is the primary platform and the only one for which ALL participating software is guaranteed to work
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS - Being phased out and not recommended
- CentOS 7 / RedHat Enterprise Linux 7
- Fedora 27
- Arch Linux
- macOS 10.13 (High Sierra) - Limited functionality only! No webservices/applications. Various optional software will not support macOS either
This concerns the platforms LaMachine runs on natively or on which you can bootstrap your own build (installation path A). The options for host platforms for simply running a pre-built LaMachine Virtual Machine or Docker container, are much larger, and also include Windows (see installation paths B & C).
In addition to a flavour, users can opt for one of three versions of LaMachine:
- stable - Installs the latest official releases of all participating software
- development - Installs the latest development versions of participating software, this often means they are installed straight from the latest git version.
- custom - Installs explicitly defined versions for all software (for e.g. scientific reproducibility).
Read more about the technical details in the contributor documentation.
How to start LaMachine differs a bit depending on your flavour.
Run the generated activation script to activate the local environment (here we assume your LaMachine VM is called stable!):
lamachine-stable-activate, this script should be located in your
If you built your own LaMachine you have various scripts at your disposal (here we assume your LaMachine VM is called stable!):
lamachine-stable-startto start the VM
lamachine-stable-connectto connect to a running VM and obtain a command line shell (over ssh)
lamachine-stable-stopto stop the VM
lamachine-stable-destroyto completely delete the VM again
lamachine-stable-activateis a shortcut that starts the VM and connects automatically, and stops the VM when you disconnect again.
If you used a prebuilt image you have to invoke
vagrant yourself from the proper directory where you did
vagrant init proycon/lamachine:stable:
vagrant upto start the VM
vagrant haltto stop the VM
vagrant sshto connect to the VM and obtain a command line shell
vagrant destroyto remove the VM
Command line access to your LaMachine Virtual Machine through vagrant or
lamachine-*-connect should be passwordless, other methods
may require a login; use username
vagrant and password
vagrant. The root password is also
these in any exposed environments!
If you enabled a webserver in your LaMachine build, you can connect your web browser to http://127.0.0.1:8080 after having started the VM.
In this example we assume your LaMachine image has the tag latest, which corresponds to the latest stable LaMachine release
(and can technically be omitted as it is the default), run
docker image ls to see all images you have available:
- To start a new interactive container, run
docker run -i -t proycon/lamachine:latest
- To start a new container with a command line tool, just append the command:
docker run -t proycon/lamachine:latest ucto -L nld /data/input.txt /data/output.folia.xml
- Add the

If you use LaMachine with docker, we expect you to actually be familiar with
docker and understand the difference between images, containers, how to commit
docker commit), and how to reuse existing containers if that is
what you need (
When you are inside LaMachine, you can update it by running
lamachine-update, if you want to add
extra software packages to your installation, run
lamachine-add first (add
--list for a list of installable packages).
You can also edit LaMachine's settings and/or directly edit the list of packages to be installed/updated with
lamachine-update --edit. Do note that
this can't be used to uninstall software.
The update normally only updates what has changed, if you want to force an update of everything instead, run
lamachine-update force=1. You can also use the even stronger
force=2, which will forcibly remove all downloaded sources
and start from scratch.
For Docker and the Virtual Machine flavours, when a SUDO password is being asked by the update script, you can simply press ENTER and leave it empty, do not run the entire script with escalated privileges.
Webservices and web applications
LaMachine comes with several webservices and web applications out of the box. Most are RESTful webservices served using CLAM, which also offer a generic web-interface for human end-users. The webserver provides a generic portal to all available services, powered by Labirinto, as shown in the screenshot below:
To start (or restart) the webserver and webservices, run
lamachine-start-webserver from within your LaMachine
installation. You can then connect your browser (on the host system) to http://localhost:8080 (the port may differ if
you changed the default value). On virtual machines, the webserver will be automatically started at boot. For
docker you can do:
docker run -p 8080:80 -h hostname -t proycon/lamachine:latest lamachine-start-webserver -f
Warning: There is currently no or poor authentication enabled on the webservices, so do not expose them to the outside world!
LaMachine comes with an installation of Jupyter Lab, which provides an excellent entry-point to LaMachine as it provides a web-based scripting environment or IDE (for Python and R), web-based terminal access, and especially access to the ubiquitous Jupyter Notebooks that enjoy great popularity in data science and beyond.
You can access your Jupyter Lab installation from the portal website of your LaMachine installation. By default LaMachine also preinstalls the interactive Python Course for the Humanities for you, so you can get started right away.
The default password for the Lab environment is lamachine, you can change this with
Warning: Do not expose this service to the world without a strong customised password as it allows arbitrary code execution and full access to your system!
Unless you explicitly opt-out, LaMachine sends a few details to us regarding your installation of LaMachine whenever you build a new one or update an existing one. This is to help us keep track of its usage and improve it.
The following information is sent:
- The form in which you run LaMachine (vagrant/local/docker)
- Is it a new LaMachine installation or an update
- Stable or Development?
- The OS you are running on and its version
- Your Python version
Your IP address will only be used to identify your country and not used in any other way. No personally identifiable information whatsoever will be included in any reports we generate from this and it will never be used for advertisement purposes.
To opt-out of this behaviour, set
private: true in your LaMachine settings.
During build and upgrade, LaMachine downloads software from a wide variety of external sources.
For a secure experience using LaMachine, take all of the following into account:
- Our recommended bootstrap procedure downloads a script and immediately executes it. This is offered as a convenience but carries some inherent risks and is generally not a secure practice. It implies a trust relation between you and us, as well as the hoster (github). Prudent users are encouraged to download the script, inspect it, and only then execute it. We may provide PGP-signed releases in the future.
- The bootstrap script asks for and requires root privileges for certain installation steps, this will always be asked and the user may confirm. The Ansible provisioning scripts also generally required a sudo, this will only be asked once, but the privileges will only be used when needed.
- Running either the bootstrap procedure or the subsequent ansible provisioning entirely as root is forbidden for security reasons.
- The current webserver configuration does not yet enable authentication for any of the webservices, so do NOT expose it directly to the internet without setting up authentication yourself.
- If you are sure you don't need a webserver/webservices, disable it in the configuration upon first build.
- The virtual machines tend to come with a preset username and password
(vagrant:vagrant), the lamachine user in Docker containers has the password
lamachine, you will need to change this.
- Do not run development versions in a production environment, always use the stable release.
- Do not run an outdated LaMachine installation, ensure you regularly run
lamachine-updatefor updates! Bugs and potential vulnerabilities may have been patched in the meantime.
- Only if your setup is otherwise secure (i.e. authentication on webservices), then make sure to always open only the necessary ports (80/443) to the internet, do not expose any of the UWSGI services to the world (this would allow arbitrary code execution).
- As per the GNU General Public Licence, we do not offer any warranty despite doing our best.
LaMachine comes in three versions, stable installs the latest stable releases of all software, development installs the latest development releases and custom installs explicitly specified versions. This section is about the latter and is for advanced users.
LaMachine itself also carries a version number, this number corresponds to the version of all the installation scripts that make up LaMachine. It is not tied to the versions of any underlying software.
In any LaMachine installation (v2.3.0 and above), you can do
lamachine-list -v to obtain a
file that explicitly states what software versions are installed. When bootstrapping a new LaMachine
installation, you can place this
customversions.yml file in the directory where you run the bootstrap, and opt for
the custom version. LaMachine will then install the exact versions specified.
You can edit this
customversions.yml file if you have good reason to opt for very specific versions of certain
packages. Instead of an appropriate version number, you can also use the strings. Do be be aware that choosing version
numbers that do not exist or combining versions of different packages that are not compatible will surely break things.
If things fail, most software providers, us included, will not deliver support on older software versions.
The purpose of this custom versioning feature of LaMachine is to aid scientific reproducibility, with it you can build
an environment consisting of older software, corresponding to the versions at the time you ran your experiments. In such
cases you should publish a version of
customversions.yml along with your data (and a copy of the installation
This custom versioning is limited, it only pertains to software that is 1) not provided by the linux distribution itself, and 2) explicitly installed by LaMachine, rather than dependencies that are pulled in automatically by package managers. Even then, certain sofware is excluded from this scheme as the upstream provider does not provide the necessary facilities for obtaining older versions, LaMachine should output a warning in the log if that is the case. It is also not supported on MacOS.
If a strict reproduction environment is desired, we strongly recommend to use the docker or virtual machine flavour of LaMachine and archive the entire resulting image.
Frequently Asked Questioned & Troubleshooting
Q: Do I need LaMachine?
A: This depends on the software you are interested in and the kind of system you are on. LaMachine is offered as a convenience but draws from other software repositories which you can also access directly.
You may want to first check if our software packages are available for your Linux distribution. For C++ software such as Frog, ucto and Timbl, we provide packages for:
- Debian Linux 9 [stretch] or higher -- Consult the package state.
- Ubuntu Linux 18.04 or higher
- Arch Linux -- https://aur.archlinux.org/packages/?SeB=m&K=proycon
- macOS (homebrew) -- https://github.com/fbkarsdorp/homebrew-lamachine/tree/master/Formula
- A final alternative is obtaining all software sources manually (from github or tarballs) and compiling everything yourself, which can be a tedious endeavour.
Python software is generally provided through the Python Package Index and can be installed
LaMachine shines as it combines a lot of software, includes complex set-ups, and handles some default configuration.
Q: Why is my LaMachine installation so big??
A LaMachine installation quickly reaches 6GB, and even more if you enable software that is not enabled by default. LaMachine is a research environment that can be used in a wide variety of ways which we can't predict in advance, so we by default include a lot of popular software for maximum flexibility. When building your LaMachine, you can disable software groups you don't want and save space.
You can also limit the size somewhat by setting
minimal: true in your LaMachine configuration, but this may mean that
certains tools don't fully work.
Disk space is also, by far, the cheapest resource, in contrast to memory or CPU.
If you use docker, be aware that you may need to increase the size limit if you build a custom LaMachine container and run into size issues!
Q: Can I run LaMachine in a 32-bit environment?
Q: Can I run LaMachine with Python 2.7 instead of 3?
Q: Can I run LaMachine on an old Linux distribution?
No, your Linux distribution needs to be up to date and supported.
Q: Can I include my own software in LaMachine?
Q: Docker gives an error: "flag provided but not defined: --build-arg"
Your Docker is too old, upgrade to at least 1.9
Q: I have another problem, can I report it?
Yes! Please report it in our Issue Tracker after checking that the problem has not already been reported (and solved perhaps) by someone else. Note that this is only for problems relating to the installation and availability of the software; for bugs or feature requests on any of the participating software (including our own), you should use the issue trackers pertaining to those software projects.
